AA/AMPS copolymer

AA/AMPS copolymer (CAS 40623-75-4) is a synthetic anionic polymer combining acrylic acid and AMPS monomers, commercially recognized under the name Acrylic acid-AMPS copolymer. It functions as a scale inhibitor and dispersant.

This threshold agent is designed for systems where conventional polyacrylates underperform due to high hardness, temperature, or pH conditions. In industrial water treatment, it inhibits calcium carbonate and calcium sulfate scale.

It is also effective against calcium phosphate scale in cooling towers, boilers, and reverse osmosis systems. The polymer is particularly effective at low dosage under high-stress conditions found in modern industrial plants.

Textile and paper processors use it as a dispersant and sequestrant to prevent mineral deposition during dyeing and bleaching operations. This protects equipment and improves process consistency across various manufacturing stages.

Home care and industrial cleaning formulations incorporate it as a builder and anti-redeposition agent in detergents. Its sequestration capacity reduces reliance on phosphates, supporting more sustainable cleaning solutions.

Personal care manufacturers apply it as a rheology modifier and stabilizer in gel-based and emulsion systems. It improves texture and the suspension of insoluble actives in various cosmetic and hygiene products.

AA/AMPS copolymer is supplied primarily as an aqueous solution, with active content typically ranging from 40% to 50%. Technical grade is the standard offering for water treatment and industrial applications.

Specifications vary by molecular weight and monomer ratio, which should be confirmed with suppliers based on the target application. This ensures the polymer meets the specific performance requirements of the end user.
